toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse
function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString
to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
@override
String toString() {
switch (this) {
case Operator.equal:
return '=';
case Operator.notEqual:
return '!=';
case Operator.like:
return 'like';
case Operator.notLike:
return 'notLike';
case Operator.greaterThan:
return '>';
case Operator.greaterOrEqual:
return '>=';
case Operator.lessThan:
return '<';
case Operator.lessOrEqual:
return '<=';
default:
return '=';
}
}
